The discovery of a mastodon skeleton in Fulton County, Ohio provided an opportunity to study the molluscan fauna and Late Wisconsinan history of this area. After the deposition of Lake Maumee sediments, a series of ponds developed in a beach ridge of Lake Maumee II, later to be filled in with sediments and vegetation. Eleven stratigraphic sections taken from a site in the village of Winameg exposed a lens-shaped deposit of shell marl capped by humus. Seventeen species of mollusks including four ctenobranchs, 10 aquatic pulmonates and 3 sphaeriids were recovered from the marl. During the early stages of the pond, Valvata tricarinata, Fossaria obrussa decampi, Gyraulus parvus, Helisoma anceps, and Pisidium casertanum were the dominant species. Fossaria obrussa decampi, Gyraulus parvus, Pbysella gyrina, and sphaeriids were probably the significant species in the late stages of pond succession due to the ephemeral nature of the small water body.
